So, I'm going to be using my 16' seark to diver hunt - Currently it has no blind in it. I planned on just ducking down in it and sitting on the floor. Will this work? Or do I need to actually make a blind, or buy one?

Also - Me and my buddy had an idea. He can get a hold of this 8' long sheets of plexi-glass mirrors. We thought about hanging them off the side of the boat so as to reflect the water - Disgusing the boat. Would this work?

I have hunted from a boat for 40 years and have made several 'blinds' for my boat. Some blinds consisted of duck weed panels that were secured to the side off the boat via rails. I have migrated to using burlap thrown over wood rails that are secured to the side of the boat via bolts through the side wall. I have also been lazy and not put the side rails on and just draped the burlap over me in the boat. All the different 'blinds' worked well - the divers (as dumb as they are) came right into the decoys.

One thing to keep in mind - if they are dumb enough to come into the decoys while you are throwing the decoys out, then they sure don't mind what type of blind you are using.

Been out in other boats with no blinds what so ever, works fine, just don't move alot while they are coming in.
Also shoot off of big fishing boats 25'+ with no camo at all while fishing. Still get our share of birds.

I do have a canvas blind on my boat so we can move around with only our heads sticking out.

Thousands on the boat.
Hundreds on decoys.
Time away from the wife....priceless

Another word of caution: If you affix anything that is not readily removable from the sides of your boat, then make darn sure you have enough hoespower to overcome the wind. You will find yourself in one big world of hurt. Your sides will become sails and your undersize motor will not be able to steer the boat.

Well, the idea with the mirros was to hang them over the side, so they drape in the water, and so they dont go over the top edge of the boat - Like hanging them by rope so you can pull them up and in real quick.
